The invention relates to a reactor for industrial plants, e.g. for an ammonia synthesis plant, comprising several catalyst beds in series charged by a radial gas flow. The object is to provide for a uniform gas flow through the catalyst bed along its entire height, otherwise different space velocities are experienced within the catalyst bed involving irregularities in the reaction. The problem is solved when the cross-section of the annular space for the effluent reaction gas flowing in axial direction is equal to or larger than the cross-section of the annular space for the influent fresh gas flowing in axial direction.
